Using controlled infection experiments this study provides evidence that incorporation into marine planktonic substrates (i.e., phytoplankton cells and, to a greater extent marine aggregates) significantly promote intake of the pathogenic bacterial strain V. aestuarianus 02/041 by the Pacific oyster Crassostrea gigas maintained under stressful conditions in the laboratory resulting in a compromised health status of the infected animals.

Environmental Microbiology Reports, EarlyView. Antibiotic resistance (AR) in bacteria is an urgent and global health issue, encompassing clinical, agricultural, terrestrial and aquatic environments. AR is not only expressed through genetic resistance. It is also found in bacteria in a small fraction of populations exhibiting antibiotic ‘persister’ states, thereby acting as a reservoir for re-growth.

Environmental Microbiology Reports, EarlyView. Summary

Environmental Microbiology Reports, EarlyView. The present study reported the antimicrobial susceptibility trends, virulence genes, and drug resistance genes of Vibrio cholerae O1 strains isolated from outbreaks and epidemics over two and half decades (1995–2019) from Odisha, India. Antimicrobial susceptibility testing was performed by disc diffusion method. Virulence and drug resistance genes were detected by multiplex PCR assays. All V.

The environmental reservoirs of different serogroups of V.cholerae causing cholera in the flowing freshwater bodies of the tribal areas of Odisha are not known. So the present study was conducted from June‐2017 to March‐2020 to find out the environmental reservoirs of V.cholerae serogroups in the water and plankton samples collected from the river, nala, stream and chua from Rayagada district.

V. cholerae form biofilm, which is essential for their survival under harsh environmental conditions. The eDNA produced during biofilm formation and interaction with other components like vibrio polysaccharide is less studied in Vibrio cholerae despite its importance in biofilm structure and stability. In this study, we selected two strains of V. cholerae, which produced sufficient extracellular DNA in the biofilm, for characterization and studied its interaction with vibrio polysaccharide.

Vibrio cholerae O1, a natural inhabitant of estuarine environments, is found in a dormant, viable but nonculturable (VBNC) state during interepidemic periods. Although the individual roles of abiotic factors affecting VBNC formation have been extensively studied, their interplay in driving this phenomenon remains largely unaddressed. Here, we identified that major abiotic factors synergize with low nutrient conditions governing entry of cells into the VBNC state. Specifically, V.

The recent emergence of Vibrio infections at high latitudes represents a clear human health risk attributable to climate change. Here, we investigate the population dynamics of three Vibrio species: Vibrio parahaemolyticus, Vibrio vulnificus and Vibrio cholerae within a British coastal estuarine site, with contrasting salinity and temperature regimes during an intense heatwave event.
